Application filed April 26, 1915. Serial No. 24,054.

I of WVashington, have invented a new and useful Siphon Flush-Valve, ofwhich the following is a specification.

The device forming the subject matter of this application is a flushtank, and the improvements to which attention is especially directedrelate to a means whereby the siphon of the flush tank is started inoperation.

The invention aims to provide a novel form of head mounted to move inthe short arm of thesiphon and constituting a means whereby at the willof an operator, a draining of the tank through the siphon may beinitiated.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to whichthe presentinvention appertains.

WVith the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawings :F igure 1 is a vertical sectional view ofthe struc ture; Fig. 2 is a cross section on the line 2-2.0f Fig. 1.

In the drawings, the numeral 62 indicates a tank and the numeral 68indicates a pipe extended through the tank and forming the long arm of asiphon, the upper end of the pipe being inclosed within a cap 64:forming the short arm of the siphon, the upper end of the pipe beingsecured to the top 65 of the cap, the pipe 63 having openings 66 locatedadjacent the top of the cap 64. The piston 67 is guided upon the pipe 63and surrounds the same, the piston work ing loosely in the cap 64 andbeing actuate by a rod 68.

The piston 67 may be lifted by means of the rod 68 and when thisoperation is carried out, a quantity of water will be lifted, the sameflowing into the long arm 63 through the openings'66 therein and servingto effect a starting of the siphon, the up-- wardly rushing waterretaining the piston head 67 elevated, until the tank has been drained.

Having thus described the invention, what is claimed is In a device ofthe class described, a tank; a pipe extended through the tank; a capinverted over the pipe and secured to the top of the pipe, the pipehaving an opening in its side wall adjacent the top of the cap; aloosely fitting piston surrounding the pipe and surrounded by the cap;and means for operating the piston.

In testimony that I claim the foregoing as my own, I have hereto afiiXedmy signature in the presence of two witnesses.
